|music an orchestral percussion instrument of 18 chromatically tuned metal tubes suspended vertically and struck near the top|
series of tuned brass (originally bronze) tubes of graded length, struck with wooden hammers to produce a sound. They first appeared in England in an 1886 performance of Arthur Sullivan's Golden Legend in Coventry. Large tubular bells were at first used as a substitute for church bells in towers. Smaller tubes were later built to be controlled from an organ manual or, in the orchestra, to be played directly by a percussionist.
